In 2010, a total of 29 candidates ran across Minnesota's eight congressional districts - good for the seventh highest per district average in the history of the state (at 3.63 candidates) across the 78 general cycles dating back to 1857. That number appears to have declined significantly with just 18 DFL, GOP, and Independence Party slots across the eight districts according to the Minnesota Secretary of State's website. The largest candidate-to-district ratio occurred in 2000 when 35 candidates ran for the Gopher State's eight U.S. House seats, or 4.38 candidates per district, followed by the Elections of 1880 (4.33), 1892 and 1992 (4.00), 1894 (3.86), and 1934 (3.67). The last time a major party failed to field a candidate in a Minnesota U.S. House race was 1976 when DFLer Jim Oberstar ran without opposition.

Collin Peterson remarked last month that he is leaning to run for reelection to Minnesota's 7th Congressional District in 2016. If he does and is victorious, he will creep even closer to the top of the list of the longest-serving U.S. Representatives in Minnesota history. The DFL congressman is only the sixth Minnesotan to win at least 13 terms to the U.S. House of the 135 elected to the chamber in state history. Peterson trails 18-term DFLer Jim Oberstar (1975-2011), 16-term Republicans Harold Knutson (1917-1949) and August Andresen (1925-1933; 1935-1958), and 14-term DFLers Martin Sabo (1979-2007) and John Blatnik (1947-1974). Andresen died in office, Sabo and Blatnik retired, and Knutson and Oberstar were defeated at the ballot box in 1948 and 2010 respectively. At 70 years, 7 months, 11 days through Monday, Peterson is currently the ninth oldest Gopher State U.S. Representative in history. DFLer Rick Nolan of the 8th CD is the seventh oldest at 71 years, 1 month, 23 days.

Congressman Nick Rahall's failed bid for a 20th term in West Virginia this cycle, combined with a narrow loss by Nick Casey to Alex Mooney in Shelley Moore Capito's open seat, means that West Virginia Democrats will be shut out of the state's U.S. House delegation for the first time in over 90 years. The Republican sweep by two-term incumbent David McKinley in the 1st CD, Mooney in the 2nd, and Evan Jenkins over Rahall in the 3rd marks the first time the GOP has held all seats in the chamber from West Virginia since the Election of 1920. During the 67th Congress (1921-1923) all six seats from the state were controlled by the GOP. Since the Election of 1922, Democrats have won 76 percent of all U.S. House elections in the Mountain State - capturing 172 seats compared to 54 for the GOP.
